【摘要】：油田勘探和開采過程中，測井是識別和評價油氣藏和解決一系列地質(zhì)問題的重要手段。它能直接把所獲得的信息和數(shù)據(jù)提供給石油地質(zhì)和工程技術(shù)人員。測井過程中使用的測井儀器的性能的穩(wěn)定是保證測井信息和數(shù)據(jù)正確性和有效性的前提條件。測井儀工作中需要貼靠井壁進行地層參數(shù)的測量，而機械臂的驅(qū)動系統(tǒng)是決定這類測井儀器性能穩(wěn)定性的關(guān)鍵部件，同時也是制約測井深度的重要難點所在。由于國外對中國出售測井設(shè)備嚴格限制，國內(nèi)現(xiàn)有的測井儀驅(qū)動設(shè)備深井下的耐高溫高壓能力差且功能單一，自主研發(fā)能夠在深井下工作的高可靠性的測井儀驅(qū)動系統(tǒng)就顯得尤為重要。 本文首先針對處于高溫、高壓、震動沖擊和泥漿的惡劣環(huán)境中工作的液壓系統(tǒng)設(shè)計的耐環(huán)境、低泄漏、微型化的設(shè)計難點進行分析研究，并設(shè)計了帶有壓力平衡裝置和碟簧補償?shù)拈]式液壓系統(tǒng)。使用AMESim仿真軟件進行了液壓系統(tǒng)仿真分析，證明了這種液壓系統(tǒng)設(shè)計的可行性。 然后，以可靠性設(shè)計思想為指導(dǎo)，，對液壓驅(qū)動系統(tǒng)進行了可靠性預(yù)測、分析，得到了系統(tǒng)的薄弱環(huán)節(jié)，明確了設(shè)計重點，指導(dǎo)液壓系統(tǒng)結(jié)構(gòu)設(shè)計。對液壓系統(tǒng)中的集成塊組件、液壓缸和平衡活塞等關(guān)鍵部件進行了結(jié)構(gòu)設(shè)計，并分析了環(huán)境溫度產(chǎn)生的熱應(yīng)力對系統(tǒng)結(jié)構(gòu)的影響。 最后，制定了研制早期階段的可靠性試驗方案，進行了環(huán)境應(yīng)力試驗和可靠性研制試驗。以一種“設(shè)計-試驗-改進-試驗”的過程，逐步發(fā)現(xiàn)設(shè)計缺陷并對其改進，提高了系統(tǒng)可靠性。地面模擬加載試驗證明了試驗樣機達到了試驗階段的技術(shù)指標(biāo)和可靠性要求，為下一步的井下試驗打下基礎(chǔ)。
[Abstract]:Well logging is an important means to identify and evaluate oil and gas reservoirs and to solve a series of geological problems in the process of oil field exploration and production. It provides information and data directly to petroleum geology and engineers. The stability of logging tools used in logging is a prerequisite to ensure the correctness and validity of logging information and data. In the work of logging tool, it is necessary to measure the formation parameters by sticking to the well wall, and the driving system of the manipulator is the key component to determine the performance stability of this kind of logging tool, and it is also an important difficulty to restrict the logging depth. Due to the strict restrictions on the sale of logging equipment in China abroad, the domestic logging tool drive equipment has poor resistance to high temperature and high pressure under deep wells and has a single function. It is very important to develop independently the high reliability driving system of logging tool which can work under the deep well. In this paper, first of all, the design difficulties of hydraulic system design, such as environmental resistance, low leakage and miniaturization, which work in harsh environments of high temperature, high pressure, vibration shock and mud, are analyzed and studied. A closed hydraulic system with pressure balancing device and disc spring compensation is designed. The AMESim simulation software is used to simulate and analyze the hydraulic system, and the feasibility of the hydraulic system design is proved. Then, under the guidance of reliability design idea, the reliability of hydraulic drive system is predicted and analyzed, the weak link of the system is obtained, the key points of design are defined, and the structure design of hydraulic system is guided. The key components of hydraulic system, such as integrated block assembly, hydraulic cylinder and balanced piston, are designed, and the influence of thermal stress caused by ambient temperature on the system structure is analyzed. Finally, the reliability test scheme in the early stage of development is established, and the environmental stress test and reliability development test are carried out. In the process of "design-experiment-improvement-test", the design defects are found and improved step by step, and the reliability of the system is improved. The surface simulated loading test proves that the test prototype meets the technical specifications and reliability requirements of the test stage, which lays the foundation for the next downhole test.
