【摘要】：石油鉆探是一項(xiàng)高風(fēng)險性、耗資巨大的系統(tǒng)工程。在鉆井施工過程中,特別是在新區(qū)和復(fù)雜層段,鉆井安全與工程事故發(fā)生的可能性時刻都伴隨著作業(yè)進(jìn)程,工程事故是威脅鉆井安全的最大隱患,工程事故發(fā)生的可能性隨時都存在,易于造成資金和時間的巨大浪費(fèi)。能否在工程事故發(fā)生的早期,給出某種程度、某種意義上的報警或警示,對于預(yù)防和控制事故的發(fā)展,最大限度地減少損失,具有重大意義,但現(xiàn)在鉆井異常事故預(yù)報技術(shù)由于各種原因還存在著預(yù)報結(jié)論不準(zhǔn)確等問題。本文正是針對現(xiàn)有鉆井工程預(yù)報存在的問題,利用綜合錄井技術(shù)參數(shù)為研究對象,開發(fā)“綜合錄井工程異常預(yù)報系統(tǒng)”,實(shí)現(xiàn)鉆井工程異常事故快速、及時準(zhǔn)確預(yù)報,主要內(nèi)容有:1.常見鉆井工程事故發(fā)生原因及表征研究。分析常見鉆井工程異常事故類型,分析產(chǎn)生的原因,研究不同類型異常事故發(fā)生時各種技術(shù)參數(shù)變化特征。2.綜合錄井參數(shù)與鉆井異常事故關(guān)系分析。介紹了綜合錄井技術(shù)發(fā)展過程,綜合錄井技術(shù)在油氣勘探開發(fā)中的作用,綜合錄井技術(shù)參數(shù)類型及檢測對象;針對綜合錄井參數(shù)與鉆井異常事故關(guān)系進(jìn)行分析,描述了不同類型鉆井異常事故在綜合錄井技術(shù)參數(shù)中的響應(yīng)特征;優(yōu)選出反映鉆井異常事故信息的綜合錄井參數(shù)。3.鉆井異常事故預(yù)報技術(shù)。根據(jù)綜合錄井異常參數(shù)特征信息,設(shè)計(jì)出不同的鉆井異常事故預(yù)報方案,形成綜合錄井工程異常預(yù)報技術(shù)。4.設(shè)計(jì)開發(fā)綜合錄井工程異常預(yù)報系統(tǒng)。在研究成果基礎(chǔ)上,提出了“風(fēng)險指數(shù)”概念,建立了“風(fēng)險指數(shù)”計(jì)算模型,編寫開發(fā)出異常預(yù)報系統(tǒng),給出了現(xiàn)場應(yīng)用實(shí)例,證實(shí)了綜合錄井工程異常預(yù)報系統(tǒng)的有效性。
[Abstract]:Oil drilling is a high risk, a costly system engineering. In the drilling process, especially in the new period of time and complex layer, possibility of drilling safety and engineering accidents are accompanied by the operation process, engineering accident is the biggest threat to safety drilling engineering accidents, the possibility always exists. Easy to cause a huge waste of money and time. Whether in the early engineering accident, given a certain degree, a sense of alarm or warning, for the development of prevention and control of accidents, to minimize the loss, is of great significance, but now the drilling accident prediction technology for various reasons there are still problems forecast conclusion is not accurate. This paper is aimed at the existing problems of drilling engineering prediction, using the parameters of comprehensive logging technology as the research object, the development of "comprehensive drilling engineering abnormal pre recorded Report system, implementation of drilling engineering accident quickly, timely and accurate forecast, the main contents are: the study of the cause and characterization of 1. common drilling accidents. The analysis of common types of drilling engineering accident, analysis of the causes, occurrence of different types of abnormal accidents of various technical parameters change characteristic of.2. comprehensive logging parameters and drilling accident relationship the analysis is introduced. The development process of comprehensive logging technology, comprehensive logging technology in oil and gas exploration and development, comprehensive logging parameters and types of object detection; according to the analysis of comprehensive logging parameters and drilling accidents, describes the response characteristics of different types of drilling accident in comprehensive logging technology parameters; optimum prediction technology comprehensive logging parameters of.3. drilling accident reflect abnormal accident information. According to the drilling characteristics of comprehensive logging parameters of abnormal signal Information, design drilling accident forecast scheme the abnormal formation of prediction system of comprehensive logging engineering abnormal prediction technology of.4. design and development of comprehensive logging engineering. On the basis of the research results, put forward the "risk index" concept, established a model to calculate risk index ", compiled developed abnormal forecasting system, application examples that confirms the validity of the abnormal forecasting system of comprehensive logging engineering.
