【摘要】：多分支水平井產(chǎn)能及干擾是采油工程,油藏工程和鉆井工程研究的重要內(nèi)容之一。隨著多分支井的廣泛應(yīng)用,研究多分支井的產(chǎn)能及干擾對(duì)優(yōu)化生產(chǎn)和指導(dǎo)鉆井都具有重要意義。在廣泛調(diào)研國內(nèi)外多分支井產(chǎn)能、干擾研究的基礎(chǔ)上,本論文通過分析不同類型多分支井及水平井的動(dòng)態(tài),針對(duì)油藏特征,對(duì)分支的數(shù)量、長度、夾角、偏心距,和地層厚度、地層非均質(zhì)性、污染系數(shù)、支間竄流、生產(chǎn)壓差等對(duì)產(chǎn)能有影響的因素進(jìn)行了初步分析,并研究了這些影響因素間的聯(lián)系。詳細(xì)介紹了目前計(jì)算多分支井產(chǎn)能的常用方法,如,模擬多分支井的油藏與井筒的耦合模型并用半解析法求解的方法和應(yīng)用解析方法模擬多分支井的方法等。本文中還給出了修正過的對(duì)稱多分支井穩(wěn)態(tài)產(chǎn)能的解析解,并用VB編制了簡(jiǎn)單的求產(chǎn)軟件。
[Abstract]:Productivity and interference of multi-branch horizontal wells are one of the important contents in oil production engineering, reservoir engineering and drilling engineering. With the wide application of multi-branched wells, it is important to study the productivity and interference of multi-branched wells to optimize production and guide drilling. On the basis of extensive research on productivity and interference of multi-branched wells at home and abroad, this paper analyzes the performance of different types of multi-branched wells and horizontal wells, aiming at reservoir characteristics, the number, length, angle, eccentricity, and formation thickness of branches, The factors affecting productivity such as formation heterogeneity, pollution coefficient, inter-branch channeling flow and production pressure difference are analyzed preliminarily, and the relationship between these factors is studied. This paper introduces in detail the commonly used methods for calculating the productivity of multi-branched wells, such as simulating the coupling model between reservoir and wellbore of multi-branched wells and solving them by semi-analytical method and applying analytical methods to simulate multi-branched wells, etc. In this paper, a modified analytical solution of steady productivity of symmetric multi-branched wells is given, and a simple software for calculating production is compiled with VB.
