A new kind of non magnetic drill collar.

In the drilling process, the drill tends to have a magnetic, having a magnetic field, the magnetic influence of the measuring instrument, can not get the correct measurement information wellbore trajectory data. To this end, the drill collar manufacturer through continuous efforts and research, to produce a new kind of non magnetic drill collar. It is the use of a low carbon high chromium manganese alloy steel, which is the result of a rigorous refining and chemical composition ratio by forging achieve its mechanical properties, good low permeability, mechanical properties of high strength, excellent resistance to intergranular corrosion cracking resistance and excellent abrasion resistance.

                      

OCTG Casing and Tubing are essential tubulars.

OCTG Casing and Tubing are essential tubulars.
Production tubing is normal nowadays into the well casing pipe in the well. Flowing wells, oil flows into the ground through the tubing into the gathering process. Apheresis wells, tubing, sucker rod deep well pump (ie, "three pumping" device) combination, the oil pumped to the surface, into the gathering process.
At the end of the sleeve is drilling down into the underground pipe, OCTG Casing  and cementing wall with cement, and then with the alignment target layer
perforating guns, the oil flow through the rock, cement, casing into the well bottom, then enter the tubing to the ground.

Sucker rod centralizers is downhole tool

Sucker rod centralizers is anti-pumping wells eccentric wear downhole tool for partial mill pumping wells, especially for rod and points or more partial grinding deviated directional wells and pumping, sucker rod and points hereinafter, with nylon rod centralizer body fit, preventing side wear better. By the coupling rod centralizer, centralizer sleeve, pup joints. Sucker rod centralizer having flexible and strong, it is in contact with the tubing wall, rod and tube may reduce friction, enhanced oil pumping life.

Part of the Drill String Components

Drilling tools drill pipe is connected to power transmission lever. Usually part of the drill string components are: drill, drill collars, drill Pipe,drilling stabilizers, special fittings and kelly. The basic role of the drill string is: (1) from under the drill bit; (2) applying WOB; (3) the transmission of power; and (4) conveying the drilling fluid; (5) special job: squeeze cement, processed downhole accidents.

Sucker rod pumping wells are elongated rod

Sucker rod pumping wells are elongated rod, then light it on the bar, then under the pump from the power transmission role. A single 7.6 or 8 meters in length, the material is generally high carbon steel, hard chrome plated, with internal threads in the hoop tubing connected on a root has been extended to an underground reservoir of the piston, reciprocating motion to pump oil through the present the oil length generally about two kilometers to the Shengli Oilfield, for example, Sucker Rod Pump Unit Controller include pumping unit, sucker rod pump

Oil field development program refers to detailed exploration from fully developed working order

Oil field development program refers to detailed AISI 4145H Crossover exploration from fully developed working order. 1. See oil exploration wells constructed belt arrangement, rapid control of oil-bearing area. 2. In the oil-bearing area has control, playing well data, understand the reservoir characteristics. 3. Subdivision stratification test oil, seek oil production parameters. 4. open production test area, to further understand the reservoir characteristics and its variation. 5. According to a comprehensive study of core, logging and well testing, production test and other information to make the reservoir stratification comparison chart, construction diagrams and fault maps to determine the reservoir type. 6. oilfield development and design. 7. According to the most reliable and stable oil drilling set basic well. After the drill is not put into operation, according to all the information well, for all the oil reservoir sand bodies were compared, and then modify and adjust the original plan. 8. After put into production wells and injection wells, collect actual production and pressure data to study, Drilling Crossover Subs to modify the original design specifications, fix a proration of each specific development period, with injection program. Due to the different circumstances of each field, the development of the program are not identical.

Drill in long-term use of corrosion and vfd speed controller wear, so that certain areas of wall thinning or presence of micro-cracks. Intensity greatly diminished, the role of external forces, most likely from the drill pipe weakest pulled off or broken.
③ processing card when drilling accident, to activities inappropriate use, when the stress exceeds the yield limit. It is deformed. Pull the drill pipe stretched thin, the stress exceeds the strength limit when. The drill will pull off.
④ resulting in the handling or use of a trauma, such as kava teeth marks, well falling matter (drill teeth, jaw) teeth caused by transverse score slips, and bruises, injured, etc. These are often traumatic stress concentration point. Thereby scaling out. And a variety of corrosion can easily start here. Cause local damage to the drill.
⑤ not tight on the buckle, the torque is not required to buckle, shoulder joints did not try to be, on the one hand shoulder losing seal. Thread likely to be drilling thorn bad. On the other hand, due to loss of shoulder support force, the male and female threads produce frequent alternating stress, fatigue thread will break.
⑥ the drilling pressure is too coil tubing drilling rig large, or the occurrence of another continuous drilling, or when a horse sticking Difficult to drill female thread swell, bursting, causing the drill off.
⑦ various connecting thread of the mating connector nipple especially for long term use and occasional breaking check that thread wear and tear caused by the drill off. You know, connecting threads are often in flux, can not check.
