Risk Factors in Oil and Gas Well Electronics Compared to Other Electronic Industries — The oil and gas well electronics industry is a low volume industry in which the development and the operating life cycles of the electronic products used is considerably longer than those of the commonly available commercial parts used to build them. Oil and gas well electronic systems, especially the ones th...

Abstract In the petroleum industry, packers refer to components/products which are used isolate one section in a formation from others, or outer of production tubing inner section, may be casing liner wellbore itself. Mechanical installed through some form movement. Permanent low cost and provide better seal. Retrievable have lower sealing capability but re-usable after repair, therefore expens...

This work aims to study the dynamic characteristics of an entire aero-engine casing by experiments using a new type rotating exciter. New vibration sensor layout rules are proposed according experimental results and transmission characteristics. The response is carried out, different measuring points also studied. finite element model engine casing’s structure established obtain natural frequen...

Abstract One of the most serious incidents that can occur in offshore drilling and exploration is damage to well structure subsea components which result uncontrolled hydrocarbon release environment present a safety hazard rig personnel. Over decades, there have been substantial developments mathematical models algorithms used analyze stresses on related define operational integrity windows ope...

Aiming at the problem that casing deformation can easily occur in tight oil horizontal well fracturing, based on rock mechanics experiments and probability statistics, distribution characteristics law of near-wellbore stress field reservoir STH M56 were solved analyzed by using finite element modeling numerical method. The research shows (1) max/min ratio is 1.2, difference less than 8 MPa, thi...

Very few reports have been presented to date on the noise and vibrational characteristics of oil injected screw compressors. This time. a series of extensive experimental analysis is performed. It includes the measurements and analysis of compressor casing vibrations. rotor shafts vibrations, torsional <rotational) vibrations. suction and discharge gas pulsations. pressure trans~ ient in one th...

A large amount of casing deformation has occurred in shale gas wells during the complex fracturing process, which affects construction and single well production. Based on statistical analysis caliper logging interpretation, main mechanism is revealed as formation slip. By comprehensively considering rotating speed under running condition, cement solidification heat release cementing fluid temp...
