钻井工程实时多参数监测控制系统的研究

钻井实时多参数监测控制系统，是对钻压、泵量等十二个参数直接测量，并对其参数进行数学建模与计算，以提高目的层采心率．以及提前预警钻进事故，在此基础上开发出专家系统对钻机运行状态进行有效控制。该系统在完成实验室检测、调试及模拟式运行后，分别在XY-44和XY-5两种型号的液压钻机上做了现场时运行，运行结果表明．该系统运行稳定，适于钻井现场复杂的钻进过程，实用性强，实现了设计目标。

A Study on Drilling Engineering Real Time Multi-parameter Monitoring System

Since a part of geophysicists take a skeptical attitude to paleo-sedimentary environment interpretation through seismic slicing, the paper considered that the seismic recording is responding results of strata elastic impedance boundary reflective stacking, if directly used in strata sedimentary interpretation will go against its physical sense, only if the seismic records after inversion processing and formed elastic impedance data, then can be used in sedimentary environment interpretation. In allusion to problems existed, discriminating from 3 sides based on seismographic theory： ①seismic slicing can be used in lithologic and/or sedimentary environmental interpretation according to wave theory; ②clarified doubts existed on geological significance of the thin interbeds seismic responding slicing; ③the postulate of slicing application is to have regional, ubiquitous energy-balanced reflected event, take the axis as the reference to study the underlying strata sedimentation. Case studies have revealed effects of lithosome and paleo-sedimentary environment interpretation through seismic slicing, illustrated feasibility and reason of the method.
