鉆孔彩色電視孔壁成像系統、直接橫波測井研究偶極子井下聲系和聲波儀、鉆孔多點滲壓儀及壓模系統、巖質高邊坡快速攝像微機地質素描成圖、層析成像技術、近壩庫段安全監測技術、邊坡監測數據處理預報軟體研究、高精度大地測量監測自動化系統等項目，研究成果內容新、先進、實用，已在工程中應用，效益顯著。A kind of measurement was developed to measure the air concentration of water and the result showed the possibility of entrained air existing near the wall of drop shaft. that is to say, the wall of drop shaft may be protected by entrained air from cavitation damage to some extent
本文設計了一種適用於近壁區水流摻氣濃度測量的方法，對空腔段水流摻氣濃度進行初步測量，發現井壁附近水流存在摻氣的可能，這對改善水流空化條件能起到積極作用。But this well was an inclined well. this is one point. this well was near to the top of holy spring mountain, considering relative altitude, its 150meters higher than koutou, but it has never dried
此井有兩處怪異：正常水井的井壁必須垂直，利於提水，而此井壁卻整體向南傾斜，這是一怪此井接近聖泉山山頂，按相對高度，幾乎等於憑高懸在口頭村上空150米處，而井水常年流溢，從不幹枯，這是二怪。The in - house system evaluation and field application showed that an excellent oil film for shielding temporary plugging could be formed near borehole wall and both plugging and recovering rates of permeability reached more than 90 % when the added amount of the broad spectrum oil film temporary plugging agent gpj reached 3 % ; skin factor decreased by 7. 4 to 10 times and production increased by 1. 82 to 2. 96 times compared with conventional technology
結果表明，當廣譜「油膜」暫堵劑gpj的加量達到3 %時，可在近井壁處形成很好的屏蔽暫堵「油膜」帶，滲透率堵塞率和恢復率皆大於90 % ，與常規屏蔽暫堵技術相比，可使油層損害程度降低7 . 4 ~ 10倍，產量提高1 . 82 ~ 2 . 96倍，而且與油層滲透率和溫度無關。This product, as an organic cationic polymer, can be used to change rheology property of the mud in the immediate vicinity of wellbore effectively and reduce wall scouring to assure stability of the borehole
該產品作為有機陽離子聚合物，可有效地改變泥漿在近井壁地帶的流變性能，降低井壁沖刷，保證井眼穩定。Stoneley wave is a kind of guide waves propagating along the liquid - solid interface in well. when a sonic beam strikes the surface of a thick plate immersed in a liquid, a stoneley wave is generated. stoneley wave approach is applied on analysis of well logging more and more widely in recent ten years with the introduction of advanced analysis methods for component waves from full - waveform array acoustic log data. the spectrum of stoneley waves are used to identify the fractured zones and quantitatively calculate the fracture parameters of reservoirs, especially to evaluate the validity of fractures at fracture - type complex reservoir
斯通利波是一種沿井壁傳播的聲波，當聲波脈沖與井壁和井內流體的界面相遇時就會產生斯通利波。近十幾年來，由於長源距和偶極子陣列聲波儀在測井中的廣泛應用和全波形陣列聲波測井資料中各組分波的處理分析方法的進步，可將斯通利波分離出來單獨研究並應用於測井資料分析。斯通利波技術是評價裂縫及其滲透性的有效方法。Due to the existence of the eddy and the abrupt bend of the stream line, the pressure on the four faces has the distribution as follow : the lowest pressure appears at several centimeters after the angle point along the top boundary, the highest pressure appears near the center line of the vertical shaft on the bottom boundary, near the angle point, the pressure on the inner boundary decreases with the decreasing height, the pressure on the external boundary decreases slightly in the right - angle region, and increases obviously near the corner
迴流漩渦的存在，以及直彎處流線的急劇彎曲，導致壁面壓力分佈在上表面距彎點一定距離后出現壓力最小值，下表面上，在豎井中心線略偏下游的位置出現壓力最大值，豎井內表面接近彎點處出現壓力沿程降低的現象，豎井外表面壓力在進入直彎后先是沿程略有降低，在直彎角落處又明顯升高。分享友人
