( Conversation Between an Engineer and Floor Man工程师与钻工对话)
1 Floor Man: One type of bottom hole assembly is used to hold(maintain) the angle. What is it called?
Engineer: It is called the rigid, packed hole assembly.
钻工: 钻井工作中稳斜用钻具组合叫什么?
工程师:刚性满眼钻具组合。
2 Floor Man: Does the pendulum drill-assembly prevent well deviation?
Engineer: Yes, it can straighten the hole. The tapered drill-assembly can be used to prevent well deviation.
钻工: 钟摆钻具组合可以防斜吗?
工程师: 可纠斜,塔式钻具组合可用于防斜。
3 Floor Man: Can we prevent the well from deviating with proper use of the centralizer?
Engineer: Yes. The centralizer has the function of anti-deviation, control and deviation building up.
钻工: 合理使用扶正器可以起到防斜作用吗?
工程师:是的,既可起到防斜和稳斜作用,又可以起到增斜作用。
4 Floor Man: The longer the bottom-hole assembly is, the better, isn’t it?
Engineer: No. The reasonable length of the bottom-hole assembly depends on the weight on bit. Normally, the maximum weight on bit is roughly equal to 70% of the total weight of bottom-hole assembly.
钻工: 井下钻具组合越长越好吗?
工程师:不,一般情况下,最大钻压为井下钻具组合总重量的70%就够了。
5 Floor Man: Is drill string assembly for coring operation up to the standards without a packed-hole centralizer?
Engineer: Yes, normally the full-hole stabilizer is not used during coring operation in order to avoid down hole complicated conditions.
钻工: 取心钻具组合不使用满眼扶正器可以吗?
工程师:可以。
6 Floor Man: Normally a stabilizer is not used as part of the drifting drilling assembly, right?
Engineer: No, it isn’t. But a drilling jar has to be used.
钻工: 通井钻具组合一般不用扶正器吗?
工程师:是的,但必须使用随钻震击器。
7 Floor Man: Where is a drilling jar fixed?
Engineer: It is fixed on the heavy wall drill pipe.
钻工: 随钻震击器一般安放在什么位置?
工程师:安放在加重钻杆上。
8 Floor Man: What is the main function of a shock absorber?
Engineer: To reduce the excessive impact on a drilling bit so as to prolong the life of the bit.
钻工: 减震器的主要功能是什么?
工程师:减少钻头过大的冲击载荷,增加钻头使用寿命。
9 Floor Man: What kinds of drilling tools does a fishing assembly consist of?
Engineer: It normally consists of make-up sub, safety sub, drilling jar, drill collar and accelerator.
钻工: 打捞钻具组合一般由哪些钻具组成?
工程师:一般由对扣接头、安全接头、震击器、钻铤和加速器组成。
10 Floor Man: Where should we fix the slip socket while fishing?
Engineer: At the bottom of the drill-string assembly.
钻工: 用卡瓦打捞筒打捞落鱼时把它安放在什么位置?
工程师:安放在钻具组合的最下部。
11 Floor Man: How do you use the heavy wall drill pipe properly?
Engineer: The 150m heavy drill pipe shall be used when the deviation angle is between 0°-35°, the 250-300m heavy drill pipe be used between 35°-80°, and the 300-400m heavy drill pipe be used at 80° and above.
钻工: 如何合理使用加重钻杆?
工程师:井斜在35°以内时可使用150m加重钻杆,35°—80°之间时使用250m到300m加重钻杆,井斜大于80°时、使用300米到400米加重钻杆。
12 Floor Man: What does a turbo drilling assembly consist of?
Engineer: It consists of drilling bit, turbo drilling tool, bent sub, non-magnetic drill collar, six drill collars and twelve heavy wall drill pipes. 钻工: 动力钻具组合组成是什么?
工程师:动力钻具组合组成为:钻头-动力钻具-弯接头、无磁钻铤、钻铤6根、加重钻杆12根。
13 Floor Man: For S135 drill pipe, do you know what S135 means?
Engineer: S135 means that the tensile strength is 135PSI.
钻工: 你知道S135型钻杆型号的含义吗?
工程师:S135表示抗拉强度为135PSI。
14 Floor Man: Can we pull out of the hole without using the safety slip?
Engineer: No.
钻工: 起钻铤时可以不用安全卡瓦吗?
工程师:不可以。
15 Floor Man: How can the derrick men put the big size drill collar into the finger board while tripping to BHA?
Engineer: Derrick men can pull drill collar into the finger board by using the small hoist.
钻工: 起钻到井下钻具组合时,井架工如何将大钻铤拉进指梁?
工程师:井架工可使用小气葫芦将大钻铤接入指梁。
16 Floor Man: Normally, where is the neutral point during drilling operation?
Engineer: It is on the drill collar or heavy drill pipe.
钻工: 钻进时,中和点一般在什么位置?
工程师:在钻铤或加重钻杆上。
17 Floor Man:How often is an inspection for defects of downhole drill-tool assembly be taken? How often is the BHA inspected?
Engineer: Once every three months for continuous operation.
钻工: 井下钻具组合一般多长时间探伤一次?
工程师:连续施工时,每三个月对钻具组合探伤一次。
18 Floor Man: Why is a mud non-corrosive ring placed in the drill string assembly during drill operation?
Engineer: To measure the corrosion of the drill string caused by the drilling fluid.
钻工: 钻进中为何在钻具内放一泥浆腐蚀环?
工程师:用于检测泥浆对钻具的腐蚀程度。
