【摘要】：M凹陷位于中國石油海外區(qū)塊,2010年潛山成為該區(qū)勘探的目的層之一,已經(jīng)成為增儲(chǔ)上產(chǎn)的重要方向。隨著勘探工作的不斷深入,潛山儲(chǔ)層的復(fù)雜性也逐漸顯示出來。巖心分析顯示,該區(qū)巖性相當(dāng)復(fù)雜種類多達(dá)40多種,儲(chǔ)層主要儲(chǔ)集空間有構(gòu)造裂縫、構(gòu)造-溶解縫、破碎粒間孔及溶孔,儲(chǔ)集空間類型多樣。如何利用測井資料識(shí)別巖性和儲(chǔ)層成為急需解決的技術(shù)難題。本文從巖心分析出發(fā),明確M凹陷潛山巖性地質(zhì)學(xué)分類,在此基礎(chǔ)上總結(jié)該區(qū)巖石測井響應(yīng)特征,確定了巖性測井分類,并提出了利用測井曲線識(shí)別巖性的方法和標(biāo)準(zhǔn);綜合分析常規(guī)、聲電成像等測井資料,結(jié)合試油結(jié)果,提出了潛山儲(chǔ)層識(shí)別和分類的方法和標(biāo)準(zhǔn);利用三孔隙度測井資料,結(jié)合巖心分析資料,提出了三孔隙度最優(yōu)化組合計(jì)算儲(chǔ)層孔隙度的方法;通過巖石分布規(guī)律、巖石力學(xué)特征和裂縫發(fā)育情況的分析,明確了混合崗巖類、酸性巖、混合片麻巖為本區(qū)的優(yōu)勢巖性,較易發(fā)育儲(chǔ)層。建立了一套M凹陷潛山儲(chǔ)層的測井評(píng)價(jià)方法和標(biāo)準(zhǔn),在勘探開發(fā)中取得的了良好的效果�？勺鳛樵搮^(qū)潛山地層測井解釋先導(dǎo),為該區(qū)儲(chǔ)量的落實(shí)提供了依據(jù),為該區(qū)潛山進(jìn)一步勘探開發(fā)提供測井技術(shù)支持。該研究成果將對(duì)中石油海外區(qū)塊的潛山測井評(píng)價(jià)具有借鑒意義。
[Abstract]:M sag is located in CNPC overseas block. In 2010, buried hill became one of the target layers of exploration in this area, which has become an important direction of increasing reservoir and production. Core analysis shows that there are more than 40 kinds of complex lithology in this area, and the main reservoir spaces are structural fractures, structure-dissolved fractures, broken intergranular pores and dissolved pores. Reservoir space types are diverse. How to use logging data to identify lithology and reservoir becomes a technical problem that needs to be solved. This paper makes clear the classification of lithology and geology of buried hill in M sag based on core analysis. On this basis, the response characteristics of rock logging in this area are summarized, the classification of lithologic logging is determined, and the method and standard of lithology identification by logging curve are put forward. Based on the analysis of conventional, acoustic and electrical imaging logging data and combined with the results of oil testing, the methods and standards for identifying and classifying buried hill reservoirs are put forward. Based on the three porosity logging data and the core analysis data, a method of calculating reservoir porosity is put forward by the combination of three porosity optimization. Through the analysis of rock distribution law, rock mechanics characteristics and fracture development, the dominant lithology of mixed granite, acid rock and mixed gneiss is determined. A set of logging evaluation methods and standards for buried hill reservoir in M sag have been established, and good results have been obtained in exploration and development, which can be used as a guide for logging interpretation of buried hill formation in this area. It provides a basis for the implementation of reserves in this area and provides logging technical support for further exploration and development of buried hill in this area. The research results will be useful for the evaluation of buried hill logging in CNPC overseas blocks.
